PyTorch Implementation of MIMO (ICLR 2021)

MIMO-pytorch

PyTorch implementation of MIMO proposed in Training independent subnetworks for robust prediction.

Model Training

python train.py

Experimental Results

For convenience, I trained small CNN-based models on MNIST for 10 epochs unlike the original paper. Note that the result below is not thoroughly verified. If you want to make some significant results, belows will be helpful:

1. Tune some hyperparameters.
2. Use harder datasets like imagenet or CIFAR-10 like the original paper.
3. Check the test set performance.

Valid set Accuracy

The number of subnetworks (M)	Valid Set Accuracy
1 (Baseline)	99.19%
2	99.27%
3	99.21%
4	99.26%
5	99.17%
